Operation Zarb-e-Azb was a joint military offensive conducted by the Pakistan Armed Forces against various militant groups, including the Tehrik-i-Taliban Pakistan (TTP), the Islamic Movement of Uzbekistan, the East Turkestan Islamic Movement and Lashkar-e-Islam. The operation was launched on 15 June 2014 in North Waziristan along the Pakistan-Afghanistan border as a renewed effort against militancy in the wake of the 8 June attack on Jinnah International Airport in Karachi, for which the TTP and the IMU claimed responsibility. As of 14 July 2014, the operation internally displaced about 929,859 people belonging to 80,302 families from North Waziristan.
